BOX-MAKING MACHINE.

Specification of Letters Patent.

Patented Apr. 26, 1921.

Application tiled August G, 1920. Serial No. 401,732.

To ai] in ii om t may come-vai.

-Be it known that I, HERBERT J. SAUVAGE, a citizen of the United States, and a resident ot' Chicago. in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Box-Making Machines, oi which the following is a speci iii-ation.

This invention relates to vimprovements in box making machines, and more particularl)J to a machine adapted for use in carrying; out a delinite operation in the manufacture of a completed box. to-ivit: the i'orming of a blank, properlyr cut and'scored aloner the fold lineeV into box-like forni, ap plyinnl a reinforcing` strip around the sides of the box. and covering the sides, surrounding margins, and portions of the in side surface of the box with a coatingl er covering of paper, such as will provide a suitable finish in the appearance of the box.

The machine hereinafter fully described and illustrated as a preferable embodiment of the invention is more especially designed to be used in the manufacture of the body or containing;` portions of the boxes or cartons ordinarilgv used in the packing of packages ot chewing-,gum for displayT purposes. These boxes or cartons are ordinarily oi oblong shape. rather shallow in dept-h, and preferablyhaving a double or hollow Wall construction throne-hout the longer side walls oi the box, this type of box being preferred b v manufacturers of chewing-gum for the reason that the contents are better preserved and protected in shipment and provides a more attractive and suitable container for displav purposes. The complete box is provided with a hinged lid or cover, although it ifa to be und rstood that the machine oi the present invention operates only on thc body of the box. preparing that part of'. the box for the addition of the hinged cover and the application of the desired labels bearing; the lithogranhic matter per tainingr to the nature andV origin of the goods.

The object ot this invention is to provide a construction for amachine which Will rapidly and eiiicientl)v accomplish the several operations in the manufacture et the compieted box for which it is designed.` and to thereby replace hand labor heretofore employed in carrying ont the same operations. A further object of the invention is to provide a machine which will not only afifeoniplish those operations heretofore carried ont by hand, but to arrange and design the moving parts ot' the machine With such degreeot' accuracy and precise cooperation as to insure the necessary sequence of operations to lolloW each other accurately in peint of time, that a box may be continuously advanced through the machine and operated upon without the assistance of linman agencies. Not only is it proposed that the several operations Will follow one another with certain sequence, but that two or more operations may be carried on simultaneously Without interference or confusion.

The preferred construction of the machine embodying the invention is hereinai'tci'fnlly set forth and completely illustrated in the accompanying drawings, wherein- Y Figure 1 is a front view of the complete machine showingr the general arrangement and relation of the different parts;

Fig. 32 is a similar view of the folding and sealing mechanism after the completion of the sealing operation and immediately before the same is removed from the box.

Referring in a more general way to the machine, the different operations accomplished by the machine and the form of box or container and the material applied to the box, it is to be understood that a number of blanks are fed to the machine, each blank being removed from a feed hopper and advanced step by step through the machine, the said blank coming to rest at each step, and during the period of rest one or more operations are accomplished, although in some instances, a definite operation is accomplished during the movement of the blank from one position or step to another.

The blank for which the machine herein illustrated is particularly designed to operate upon, comprises a rectangular bottom wall A, end walls B, of a single thickness of material, separated from the bottom wall A by means o score lines a, and side walls C of the double or hollow wall structure heieinbefore indicated. These hollow Side walls are preferably formed by folding the side marginal portions of the blank along parallel score lines c, there being formed a marginal flap o?. TWhen the hollow sides are folded there are formed two spaced walls e, e, a connecting top wall f parallel with the bottom wall A of the blank, the end flap ai being glued or otherwise secured tothe bottom wall A of the blank. TheI blank is fed to the machine in knockdown form, that is, the end walls extend outwardly in the plane of the bottom wall and the hollow side walls C are folded inwardly toward each other and against the bottom wall A so that the blank is substantially flattened out, as shown in Fig. 4.

The first major operation to be aecomplished is that of forming or folding the blank into its final shape to receive the covering layer of paper, and the second major operation to be accomplished is that of applying the paper having previously received a coating of glue, or other suitable adhv sive, to the folded blank. The first major operation may be termed the preparatory operation. and includes a number of successive operations which may be described as those operations which bend or break the blank along the score lines, thereby enabling the forming; of the blank into box form to he accomplished more readily, and then the actual folding of the blank into box-like form. The second major operation likewise consists of numerous subordinate operations by which the blank is applied to an arbor carried on an endless carrier and advanced through several positions` during which a strip of gummed paper is applied to the sides of the box and pressure applied to insure proper adhesion and smooth finish by means of brushes or wipers, the overlapping edges of the paper folded against the bottom wall of the box, the overlapping margins of the paper surrounding the up per edges of the box are cut. folded inwardly and downwardly against the inside surface of the box and properly secured by means of brush wipers, and finally discharged from the machine. To accomplish all of these various steps and operations, a multitude of reciprocating` oscillating, and rocking members are employed, all of these members beinpp driven from a single source of power, such as a motor, the motor having;r driving connection with the main driving shaft uponY which are mounted properly designed cam members which transmit to the parts which actually engage the blanks, the proper movement and at the proper time. The blank engaging parts are connected to their respective cams b v means of intermediate links and levers, although in many instances two or more blank engaging parts are operated by a single cam. These cams are designed to produce the desired motion and are likewise cordinated with respect to each other as to operate their blank engaging members at the proper instant. For the most part, these cam members produce an intermittent motion inasmuch as the members operated thereby( operate on each of the blanks asthey are successively advanced through the machine.

Considering those parts which enter into the construction of the machine, although not forming the vital operative parts thereof, a frame 1 having the form of av table having legsf andcross members 3 supports on its top surface' a'foundation plate 4 upon which are bolted or otherwise secured other frame members which carry the various operating elements.

Journaled in bearings formed at opposite ends of the table and below the top surface thereof is a shaft 5 provided at one end with a large gear wheel 6. Above the shaft and extending parallel with it is a drive shaft 7 having a pinion 8 meshing, with the gear wheel G of the driven shaft 5. At the opposite end of the driving shaft 7 and beyond the end of the frame 1 is a large gear wheel 9 to which power is transmitted by means of a motor 10 suitably mounted upon the foundation plate or bed 4, said motor being operatively connected with the gear wheel 9 through the medium of a train of gear wheels 11, 11 mounted on a shaft journaled in a bearing bracket 12 and meshing with the `gear wheel 9 and the pinion i3 keyed to the armature shaft of the motor. At the extreme end of the driving: shaft T is a hand wheel 14. Preferably mounted between the gear wheel 9 and the driving* shaft 7 proper, is provided a clutch 15 of any suitable construction and operative by means of a lever (not shown)V within reach of the operator to enable the machine to he stopped without stoppingr the motor.

'Upon the driven shaft 5 are keyed a series of cam plates, generally of circular form, though varying in size and conformation, and likewise varying in their angular relation in order to produce the desired motion at the proper time. These cam wheels are designed to produce in general two types of movement, namely, a vertical reciprocating movement and a horizontal reciprocating movement. Referring; to Fig. 30. there is illustrated the two types of drive cmployed in the machine. a description of which will sufiice for all of the several cam wheels. lVhere it is desired to provide a vertical reciprocatory motion, a vertical bar 16 is provided at its lower end with an L-shaped member 17 which forms a. vertical slot'straddlingr the hub 18 of a cam wheel 191 keyed to the driven shaft 5. The periphery of the caniV wheel 19 is irregular in contour and designed to transmit to the bur 1G an intermittent reciprocatory movement, said bar beingF provided with a cam roller 20 'journaled on the Lmember 17. There a horizontal reciprocatory movement is desired, a bell crank lever 21 is employed, the same beingjr journaled upon a suitable bearing Q2 fixed to the table frame 1 at a point rearwardly of the shaft At the end of the lower arm 23 of the lever 21 is a (um roller 24 engaging a cam groove 25 formed in the cam Wheel 19, and the upper arm QG extends upwardly above the foundation plate 4 and is connected to the horizontally1 reciprocae ing parts operated thereby, by means of an intermediate link 27. Although the driving
